Lubricator.



WILLIAM A. WILSON, OF SANTA CLARA, CALIFORNIA.

LUBRICATOR.

Specification of Letters Patent.

Patented J an. 24, 1911.

Application filed August 25, 1910. Serial No. 578,920.

To au whom it may concern:

Be it known that I, VILLTAM A. VILsoN, a citizen ofthe United States,residing at Santa Clara, in the county of Santa Clara and State ofCalifornia, have invented certain new and useful Improvements inLubricators, of which the following is a speciication.

My invention relates to that class of lubricators in which the oil inthe reservoir is subjected to the lifting pressure of water from acondenser, and the oil drop thus fed is subjected to the impelling andspraying action of a jet of steam from an injector, whereby it isdelivered, mixed with and atomized by said steam.

My invention consists in the novel construction and' arrangement ofparts which I shall hereinafter fully describe and claim.

Referring to the accompanying drawings-Figure 1 is an elevation, partlybroken, of my lubricator. Fig. 2 is an end View, enlarged, of thespray-pipe, showing the oil-breaker or atomizer. Fig. V3 is a sectionaldetail, enlarged, of the injector end of the spray-pipe.

l is the reservoir, provided with a filling connection 2, a drain 3, anda gage glass 4. 5 is an extension tube leading from the top of thereservoir and supporting the condenser 6, from which the pressure pipe 7leads down through the extension tube 5 and opens out into the reservoirnear its bot-torn.

Leading from the top of the reservoir 1 is the feed tube 8, to theLipper end of which is coupled the spray-pipe 9. In the end of thisspray-pipe is fitted the injector nozzle 10 of the steam or superheaterpipe 1l, which latter is controlled by a valve at 12.

13 is the pipe connection which leads steam to the condenser, and 14: isthe steam connection common to both the condenser pipe 13 and thesuperheater pipe 11. Suspended from the injector nozzle l0 of thesuperheater pipe and hanging down into the feed tube 8 1s a needle 15for the oil drop.

In the delivery end of the spray-pipe 9 is an oil-breaker or atomizerwhich consists of projections 16 extending into and somewhat irregularlyobstructing the passage of the pipe.

17 is the valve for controlling the outlet from the condenser to thepressure pipe 7.

18 is the valve for controlling the oil drop to the feed-tube 8.

In operation the oil in the reservoir being subjected to the liftingpressure of the condensed water through the pressure pipe 7, is fedupwardly into the feed tube 8, and thence is drawn by the suction of thesteam issuing from the injector nozzle 10, drop by drop onto and up theneedle 15 and thence forwardly until the drop joins the issuing steamand is mixed with and carried forward by the steam jet and delivered toits destination through the breaker or atomizer 16 in an emulsifiedspray. Superheated steam is found to give the best results as the oil isthus sprayed into the cylinder as superhcated particles in a highlyluidic state capable of reaching all surfaces.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is- A lubricator of the described classconsisting of a reservoir, a condenser having a connect-ion with asource of steam, a pressure pipe from the condenser leading down throughthe top of the reservoir, a feed-tube leading from the top of thereservoir, a spray-pipe coupled to the top of the feedtube andcommunicating therewith, a steaminjector nozzle fitted to the spray-pipeand having a connection with a source of steam, a needle for the oildrop suspended from Ythe nozzle and hanging down into the feedtube, andobstructing projections in the delivery end of the spray-pipe serving asan oil break or atomizer.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
